Please give special attention to Figure 2. In the version I see, some text remains hidden (lower left), text does not uniformly align with graphics (e.g. on the ascending side versus the descending side), etc.

Please clarify the displays of 95% CI from the bootstrapping Monte Carlo runs. In figures with red lines (Figure 2, Figure 3) identified in the labels as representing the magnitude of the 95% CI, a reader sees only a lower line, not - as most might expect. - min and max representing plus/minus 95CI. In text (lines 244, 245) authors give uncertainties in terms of days, and therefore of course always positive. But in Figs 2 & 3, one often sees negative values for 95CI and - as mentioned - only a single value rather than a range. Fix the figures, clarify that the values show by red cross hatches represent absolute values, explain how one represents 95CI with only a single line? Change something to clarify.

Thank you for very positive changes!

Please submit version with revised figures.
